Research/Academic Interests

The overarching focus of Dr. Schumann's research laboratory is to define the neurobiological mechanisms underlying aberrant cellular and molecular development of the brain in individuals with neurodevelopmental disorders, such as autism, and other psychiatric disorders across lifespan.

Over the last 18 years, her laboratory has taken a multidisciplinary approach to examining lifelong human brain development, utilizing a wide array of methodologies from longitudinal magnetic resonance imaging to postmortem cellular and molecular techniques.

Dr. Schumann is also director of two human brain tissue collection programs: the Brain Endowment for Autism Research Sciences (BEARS, founding site of Autism BrainNet) and Brain Endowment for Mental Health to support research on schizophrenia disorders.
